Matthew Emmons/USA TODAY SportsFormer five-star prospect Jackson Jeffcoat finished his career as the best defensive end in the Big 12.

Below is a closer look at what happened to ESPN 150 players who signed with Big 12 schools:

No. 2: Jackson Jeffcoat, DE, Texas – Though he never reached a high level of team success, Jeffcoat had a great individual end to his career, earning Big 12 co-Defensive Player of the Year honors and leading the league with 13 sacks.

No. 4: Jordan Hicks, LB, Texas – Hicks has been good when he has played. Because of multiple injuries, that hasn’t been often. Hicks missed most of last season with a torn Achilles, just a year after also being knocked out with a hip flexor injury. After getting a medical redshirt from his 2012 season, Hicks has one more year of eligibility remaining.

No. 13: Mike Davis, WR, Texas – Davis finished in the Big 12’s top 10 in receiving the last two seasons, compiling 200 career catches and 18 touchdown receptions.

No. 14: Taylor Bible, DT, Texas – Bible never played a down at Texas, leaving after his redshirt freshman season because of issues with grades. Bible ended up at Carson-Newman.

No. 15: Ahmad Dixon, S, Baylor – Dixon had a tremendous tenure with his hometown school, earning All-Big 12 and All-American honors as a senior as Baylor captured its first Big 12 title in 2013.

No. 18: Demarco Cobbs, ATH, Texas – The Tulsa, Okla., native has appeared in 29 games on special teams and as a defensive reserve. He missed all of the 2013 season with a knee injury.

No. 20: Darius White, WR, Texas – After making just six catches his first two seasons, White transferred to Missouri. He caught just seven passes this season for the Tigers, but has another year of eligibility left.

No. 21: Tony Jefferson, S, Oklahoma – In his first season, Jefferson was the Big 12 co-Defensive Freshman of the year, and he was a three-year starter before leaving early to go pro.

No. 46: Ashton Dorsey, DT, Texas – After serving as a reserve throughout his career, Dorsey was projected to start this season, but he transferred out days before Texas’ season opener.

No. 48: Austin Haywood, TE, Oklahoma – After getting playing time as a third tight end early in his career, Haywood unexpectedly quit in the middle of the season, tried to earn his way back on the team, failed and ended up transferring to Central Arkansas. After getting suspended there, Haywood gave up football.

No. 62: Corey Nelson, LB, Oklahoma – Nelson shined early this season after finally getting a chance to be a full-time starter. That, however, was short-lived, as Nelson tore his pectoral muscle in an early October win over TCU and sat out the rest of his final season.

No. 65: Blake Bell, QB, Oklahoma – The “Belldozer” starred his first two seasons as a situational, short-yardage QB. But in the preseason, Bell was beaten out by Trevor Knight for the starting job. Bell, however, still had his moments this season because of injuries to Knight. He led OU to a win at Notre Dame, then quarterbacked OU’s game-winning touchdown drive at Oklahoma State.

No. 72: Reggie Wilson, DE, Texas – He appeared in 51 games as a defensive reserve. Wilson had 19 tackles and a sack as a senior.

No. 73: Chris Jones, WR, Texas – Jones transferred out after one year, and never played.

No. 75: Shaun Lewis, LB, Oklahoma State – Lewis made an immediate impact, earning Big 12 co-Defensive Freshman of the Year honors along with Tony Jefferson. Lewis was a four-year starter and a big piece in Oklahoma State’s defensive turnaround this season.

No. 77: Quentin Hayes, S, Oklahoma – After serving a year-long suspension, Hayes returned to win a starting job this past season. He has another year left.

No. 86: Tevin Jackson, LB, Texas – Jackson has been a backup linebacker for the Longhorns and will be part of the team’s great depth there in 2014.

No. 103: Adrian White, CB, Texas – Played in 17 games, then joined the mass transfer exodus from this Texas class.

No. 109: Ivan McCartney, WR, West Virginia – McCartney never became a No. 1 receiver, though he did contribute on West Virginia’s explosive offenses in 2011-12. He only had 12 catches this past season as a senior, however.

No. 114: Aaron Benson, LB, Texas – The cousin of former Texas running back great Cedric Benson has only been a contributor on special teams.

No. 122: Carrington Byndom, S, Texas – One of the few players from this Texas class to pan out. Byndom made 39 career starts and was a second-team All-Big 12 selection this past season.

No. 129: Brennan Clay, RB, Oklahoma – Clay proved to be a reliable and steady force in the OU backfield. He finished his career with 1,913 rushing yards, including 957 in 2013.

No. 134: Adrian Philips, ATH, Texas – Phillipssettled in the Texas secondary, collecting 28 career starts there. He was second on the team this past season with 82 tackles.

No. 141: Trey Hopkins, OG, Texas – Hopkins became a stalwart up front, making 42 career starts along the offensive line. He was a two-time, second-team All-Big 12 selection.

No. 142: Justin McCay, ATH, Oklahoma – McCay transferred to Kansas after two years in Norman. He had nine receptions and a touchdown, which also was the first scoring catch by a Kansas wide receiver in almost two full seasons.

What they’re saying: "I think we're back more to '08." – Texas coach Mack Brown, comparing this year’s squad with the one in 2008 that went 12-1.

Three things to watch:

1. For Texas to contend for a Big 12 title, David Ash must play like an upper-echelon Big 12 quarterback. Ash has the talent, and he’s shown flashes. But he’s yet to perform at that level on a consistent basis. QB play is the biggest reason why Texas has endured back-to-back mediocre seasons. But Ash takes care of the ball and makes his share of plays, the Longhorns will be dangerous.

2. The Longhorns, potentially, have the best defense in the Big 12, and one of the best in the country. Ends Jackson Jeffcoat and Alex Okafor, who combined for 15 sacks last season, will give Texas a lethal presence off the edge. The Horns also have a pair of lockdown cornerbacks in Carrington Byndom and Quandre Diggs. Defense hasn’t been Texas’ problem, and this season, it figures to be a massive strength.

3. The battle of the oranges in Stillwater on Sept. 29 will be critical for both Texas and Oklahoma State, giving the winner the inside track to compete with OU, West Virginia and TCU for the conference crown. Should Texas lose that game, the Longhorns could slip into a free fall, with back-to-back games against the Mountaineers and Sooners looming next.
